The LV-250R is a PM2.5 sampler.
- It is capable of mass concentration measurements of particulate matter PM2.5) using a filter, based on the interim measurement manual desig- nated by the Japanese Ministry of the Environment. With this sampler, airborne particulates in environmen- tal air are sucked in at a constant flow rate via a suction port.
